DESCRIPTION:
This 12-bit to 24-bit multiplexed D-type latch is built using advanced dual
metal CMOS technology. The ALVC16260 is used in applications in which
two separate data paths must be multiplexed onto, or demultiplexed from,
asingledatapath.Typicalapplicationsincludemultiplexingand/ordemultiplexing
address and data information in microprocessor or bus-interface applica-
tions. This device also is useful in memory interleaving applications.
Three 12-bit I/O ports (A1-A12, 1B1-1B12, and 2B1-2B12) are avail-
able for address and/or data transfer. The output-enable (OE2B, OE2B,
and OEA)inputscontrolthebustransceiverfunctions.TheOE2BandOE2B
control signals also allow bank control in the A-to-B direction. Address and/
or data information can be stored using the internal storage latches. The
latch-enable (LE1B, LE2B, LEA1B, and LEA2B) inputs are used to control
data storage. When the latch-enable input is high, the latch is transparent.
When the latch-enable input goes low, the data present at the inputs is
latched and remains latched until the latch-enable input is returned high.
The ALVC16260 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
